3335.png   Techspray air dusters (commonly called "canned air", "compressed air", and "dusting gas") blow away dust, microscopic contaminants, lint, metallic oxide deposits and other soils that can damage sensitive electronics. When these contaminants get in the way of vents or fans within the device, they create a build up which leads to overheating and/or shortages.

Techspray dusters do not contain additives that can contaminate sensitive electronics. Retail dusters generally have bitterant added to prevent huffing. This same bitterant can lead to unwanted and potentially harmful residues that can build up over time.
HFC-134a – Most common for industrial applications because it is nonflammable. Intended for cleaning energized circuits. 

HFC-152a – Most commonly available duster in consumer retail because it is less expensive than HFC-134a. It is flammable, and will ignite when concentrated (i.e. in liquid form) and exposed to a spark or flame. 1/10th the global warming potential (GWP) of HFC-134a. 

HFO-1234ze – A newer propellent that is nonflammable, and a much lower GWP than either HFC-134a and HFC-152a. Ideal for ISO-14000 programs.
